8 Claims. (Cl. 101-207)
This invention relates generally to rotary presses and
concerns, more particularly, systems for supplying ink
to the fountains of such presses.
With the developing use of color in newspapers, it has
become increasingly important to provide rotary presses
of the type commonly used for printing newspapers with
some means for supplying colored ink to the appropriate
portions of ‘the printing cylinders. Divided or plural ink
Iowever, it will be appreciated vthat the press unit 10
includes a primary ink supply system (not shown)
through which black newspaper ink is pipe-d to each of
the fountains l2—'19 for conventional operation of the
unit.
In carrying out the invention, a plurality of ink tanks
are mounted in cabinet recesses formed in the press unit
it). In the preferred ‘arrangement, two cabinet recesses
25 and 26 are provided, one on either side of the illus
trated operating end of the press unit ft}, with two tanks
27 and 28 mounted in the recess 25 and two tanks 29 and
30 mounted in the recess 26. Each tank is generally cy

arranged Bowden wires 95.) leading to indicators ‘93 so that
the operator of the press unit can tell at a glance how

Since the supports 5l-—54 are identical, except for being
left ‘and right hand units for mounting on oppositely fac
ing walls, only the support 54 will be described in detail
and it will be understood that the supports 5l—53 are
correspondingly constructed and arranged. The support
54 includes an upwardly opening, cup-like member 55
for embracing the bottom portion of one of the ink tanks
and which is provided with a notch 55 to receive the tank
fitting 32 and thus locate the tank in the cup-like member.
the new tank properly positioned and coupled to the con
duits 31 and ti e line 33, the tank and support are swung
back into the cabinet recess and operation of the press
may be continued.
Those skilled in the art will appreciate that the manner
in which the amount of ink in a particular tank is indi
cated is a particularly economical and efficient one. ‘It
has already been observed above that the ink system illus
trated and described makes the provision of colored ink in
a press unit a convenient, simple, and unusually clean task.
The member 55 is supported on a base 57 that includes
a rod 53 which is vertically slidable in a pair of spaced
arms 59 and 6t? forming parts of a bracket 61 that is
rigidly secured to the frame of the press unit it}. A
guide pin 62 is secured to the base 57 for sliding move

When it is desired to remove or
replace one of the tanks, the tank is pulled forwardly
from the recess until its support is snap~locked in tilted

line 33 and conduits '31 quickly disconnected so that the
tank may be lifted from the support and replaced. With

When an ink tank is placed in the member 55, it will be
appreciated that the weight of the tank and its contents will
bias the support downwardly against the force of the
spring 65. As the ink in the tank is used, the weight
lessens and the spring 65 returns the member 55 toward its
elevated position. ‘For indicating the vertical position of
